Peter Hahndorf Peter Hahndorf You are allowed to freely distribute this utility via floppy disk, CD-ROM, Internet, or in any other way, as long as you don't charge anything for this.
If you distribute this utility, you must include all files in the distribution package, without any modification! I looked at Tcpvcon. Since on GUI, we simply right click and close connection, wondering how to do the same for this command line tool? If you need to do it programmatically, use a Windows api. ZippyV, which API i should be looking at? Johnydep, Post the question on Stackoverflow. It will be answered in minutes hopefully.
My system, while TcpView is running, is super sluggish. Alt-Tab is sloooow and painful. CurrPorts, suggested by Peter Hahndorf does not have this problem. Show 2 more comments. Platform Networking. Sign in to vote. I am testing a TCP proxy with some Windows file servers and clients.
However, when under heavy workload, the clients will reset the TCP connection. However, immediately after the command is sent, the client will send a TCP reset packet to kill the connection.
This process will repeat for about 5 seconds. After that the clients will stop sending reset and the test can continue. I have no idea why the client would reset the connection immediately before the server responds anything.
I have checked the event viewer but nothing special could be found. Are there any ways to find out the reason of the TCP reset? Thank you very much. Wednesday, December 7, AM.

In the filters dialog-box, you can add one or more filter strings separated by spaces, semicolon, or CRLF in the following syntax: [ include exclude ] : [ local remote both process ] : [ tcp udp tcpudp ] : [ IP Range Ports Range ] Here's some examples that demonstrate how to create a filter string: Display only packets with remote tcp port 80 Web sites : include:remote:tcp Display only packets with remote tcp port 80 Web sites and udp port 53 DNS : include:remote:tcp include:remote:udp Display only packets originated from the following IP address range: If you have IPNetInfo with version prior to v1.
